What type of transmission is indicated by the term "NTSC?"

NTSC stands for National Television System Committee. It is the standard for analog fast-scan color television broadcasting that was widely used in North America before the transition to modern digital television (ATSC). In amateur radio, operators still use the NTSC standard for transmitting analog fast-scan television (ATV). Because fast-scan TV requires a large amount of bandwidth (about 6 MHz), it is only permitted on the 70-centimeter band and higher frequencies. Distractors mentioning satellite uplinks, compression schemes, or made-up acronyms like 'Normal Transmission mode' are incorrect because NTSC is strictly an older analog video standard, not a digital compression or satellite protocol.
